CARBURETER-ADJU'STER.

To aZZwtom t may concern: v

Be it known that Iy HERBERT A.. BERK- MAN, a citizen oit' the United States, residing at Chicago, in the county of Cook and State of illinois, haveinvented a new and usci-ul Carbureter-djnster, ot 'which the following is a specification.

i This invention relates to means Whereby a carburetor can be adjusted readily Vfrom the dashboard eta motor vehiclerone of the objects of the invention being toutilize an attachment which can be installed readilyon a car with or ivithoutan :instrument board.

i further `ohiect is'to ,provide an. attachment which does not require theuse of pivots and similar joints but has combined with it flexible shaft sections whereby the power tiansmitting` portion ot the attachment can be arranged at any angle desired ,Without interfering With the Operativeness thereof.

A still further object is to provide simple and eiiicient means for holding the attachment against accidental movement after adjustment and which clearly indicates to the driver the extent ot adjustment.

With the foregoing and other objects in view, which Will appear as the description proceeds, the invention resides in be combination and arrangement ci parts and in the details et construction hereinafter described and claimed, it being understood that, Within the scope of what is claimed. changes in the precise embodiment of the invention shovvn can be made Without degai-ting` from the spirit of the invention.`

In the accompanying;- dravvings4 the preferred form et the invention has been shown.

In said drawings Figure 1 is a section throuo'h a portion ot a motor vehicle and showing the attachment in side elevation. Y

Fig. 2 is a front elevation ot the dial and the indicator button.

Fig'. 3 is a section on line 3-3, Fig. 2.

Referring to the figures by characters oft reference 1 designates the usual rod extend` ing to the carbureter and Journaled Within the dash A ot the motor vehicle. The steering post has been indicated at B and the operating portion of the present attachment is designed to be secured tothe instrument board C or to any other part of the vehicle v at a point close to thesteering post Where it can be reached easilyby the driver. The part secured to thisinstrument board or the Specicaton of Letters atent.

pointer 9 projecting Ytrom one end thereof,`

this pointer being,` designed to register with any one ot a series of graduations 10 radiating from the recess G. The graduations may be suitably designated by means of the Words open7 and closed arranged at-mpposite sides oft afneutral or intermedi-` ate graduation 11,-there being arrows combined with. the Words to indicate direction otinovement when it is desired to open or close the adjustable `portion ot the carbu-V Wreter.

Y secured to the dish 7 so as to rotate therewith is stern 12 extending through the opening' 5 andhaving its iree end portion screw threaded as at 14. A nut 1e and a loch nut 15 are mounted on this threaded portion and a coiled spring; 16 is arranged onv the stem 12 between the nut 1st and the boss 41 and it ivill'be obvious that this spring; serves to bind the disk 7 against the plate 2 so that the pointer 9 will be held by triction in any position to which it may be turned. By means of the nuts 14: and 15 the tension et the spring' can `be regulated.

The threaded end portion 13 of the stem 12 is soldered or otherwise secured to a.

sleeve 17 in which is soldered one end of' a short flexible shaft section 18. The other end et this shaft section is soldered or otherwise secured Within a sleeve 19 soldered or similarly fastened to one end of a rod 20. Another sleeve 21 is secured to the other end of the rod and to one. end of a shortY flexible shafts permit of the placingcot'Y the parte at sharp angles which heretofore have required the use oi universal joints iin and other expensive connections Which get out of order easily. By utilizing the spring a simple means is employed for holding the parts in adjusted positions, it being unnecesary, with the construction shown, to utilize separate friction Washers or the like. With this construction of attachment there is no lost motionin the actuating of the rod l such as occurs Where springs are employed as part of the transmission connection in lieu of flexible shafting.

lfVhat is claimed is l. A carbureter adjusting attachment for motor vehicles comprising a rod, a flexible shaft section secured to each end of the rod, means for securing one of said sections to the carbureter rod, acombined indicator and actuating member connected to the other shaft section,fand adjustable resilient means for holding the actuating member against free rotation. j

' 2. A carbureter adjustingvattachment for motor vehicles including a dial plate, a finger piece mounted for rotation thereon and including a pointer, a stem projecting fromr the linger piece and through the dial plate, resilient means adjustably mounted on the stem for binding the finger piece upon the dial plate tovhold said finger piece against accidental rotation, a rod, a exible shaft section connecting the rod to the stem, a coupling sleeve, and a flexible shaft section connectingy said sleeve to the other end of the rod.

' 3. A carbureter adjusting attachment for motor vehicles including a dial plate having a recess, afinger piece mounted for rotation in the recess and including a pointer, a stem extending from the finger piece and through the-dial plate, resilient means on the stem for bindingthe ingerpiece Within the recess to hold the pointer against accidental rotation, a'rocl, a flexible shaft connection between one end of the rod and the stem, a flexible shaft section connected to the HERBERT A.
